What got your goat this morning?

I was having a perfectly nice morning - walked the dog, read me book, played some PlayStation with the youngest and then went shopping.

Perfectly good, mostly empty car park and then some twat in a training suit decides to park his VW Up in the aisle instead of in one of the many, many parking spaces and stroll into the supermarket. Now everyone has to go around it.

It's been half an hour and I'm still annoyed about the sheer selfishness/rudeness of it all. Right spoiled my morning. Anyone else in a similar boat?
